I generally don't wear kajal/kohl on my waterline unlesss I'm seriously digging into an ethnic mode,so I would be seeing it more as a pencil eyeliner than kajal.
To begin with the supreme black tagline did ring a bell only to be found an exaggeration later on and similar was the claim of 12hr.
It's neither jet black nor THAT long lasting!
I find the maybelline's colossal and lakme iconic ones way better than this.
It does't smudge easily but the pigmentation is so poor that my heavens know how many swipes I needed to get a decent black eyeliner kinda effect..phewww!!!
I won't recommend this specially when there are so many kajals/kohls/pencil eyeliners available in the market in the same price bracket!
